When that happens it may mean that you should put it aside for a while. Maybe you should take some time to get involved with other art forms or anything else. Or if you’re working a day job maybe take some time to just enjoy life and be grateful that you have a job, or take that as an opportunity to start working towards that promotion at work that you have always wanted. Above all the main thing to do is just step back from it until you feel the time has come to start it again.
In some cases the art world does go through its phases. Sometimes things slow down and pick back up again and so on. But if you’re not enjoying it then you’re just wasting your time. Remember my Professional Artist Cycle? The first you have to love it and then comes producing and promoting it.
